- FIGS. 3a and 3b show in exploded view the locking element of FIG. 2 shown in two different stages of operation of the device according to the invention.
- FIG. 3c shows an exploded view of the locking element according to the invention before its mounting on a fixed plate transversely to the forward surface of the microwave oven.
- a microwave oven comprises a cooking chamber, not shown, whose side walls bear reference numeral 1.
- a forward surface 2 of the microwave oven comprises an opening giving access to the cooking chamber.
- a movable door 3 hinged on the forward surface 2 is adapted to close completely the cooking chamber.
- the movable door 3 comprises a closing system, for example, at least one hook 4 secured, for example, immovably on the door and permitting effecting complete closing of the door; this hook comprises, for example, an actuating nose 5 and a catch 6.
- the catch 6 has for example an inverted U-shape, the curved portion of the U being slightly modified so as to create a slight slope rising in the direction of the nose and facilitating the sliding of the locking element 7 of the microwave oven.
- the actuating nose has, for example, a thickness e the same as hook 4, a width 1 and a neck 8 sufficiently wide to avoid any flexibility of said nose during contact of the nose on the locking element 7 of the microwave oven.
- the forward surface 2 of the microwave oven comprises, in addition to a first opening 9 permitting the hook 4 of the movable door 3 to penetrate so as to come into engagement with the locking element 7, other openings of which a single one 10 is shown in FIG. 1, these openings permitting, for example, by securement tongues 11, 12 and 13, the positioning of a plate 14 supporting, among other things, the locking element and an operating switch 15 for the microwave oven, plate 14 being fixed transversely to the forward surface 2 of the microwave oven between one of the side walls 1 of the cooking chamber of the microwave oven and the locations 16, 17, 18 and 19 provided for the reception of a control panel, not shown, and containing, for example, components determining the instructions as to time, power, rapid cooking with timing control, and of actuation of the apparatus.
- the locking element 7 fixed on the plate 14 is constituted for example by a wheel 20.
- the wheel 20 is mounted rotatably on plate 14 about a shaft 21 located parallel to the forward surface 2 of the microwave oven and integral with the plate 14.
- Wheel 20 comprises moreover two opposite surfaces A and B of which only one A is visible in FIG. 1.
- the first surface A comprises, for example, two abutment lugs 22 and 23, a first abutment lug 22 located in the path of nose 5 of hook 4 of the movable door 3 and a second lug 23, located near edge 22' of the first surface A and angularly displaced relative to the first lug 22 to avoid any abutment of the nose 5 with the second lug 23 during closing of the movable door 3, as well as an arcuate slot 23' disposed angularly between and below the two abutment lugs 22 and 23 and receiving a safety spur 24 positioned transversely of the first surface A of the wheel 20 and constituting moreover a blocking finger member 25 (shown in FIGS.
- the blocking finger 25 is an element of a safety lock comprising moreover a stop boss 26 integral with the plate 14 and disposed facing the second surface B of the wheel 20.
- the blocking finger 25 is movably mounted under the action of elastic means constituted for example by a coil tension spring 27 (shown in FIGS. 3a to 3c), secured on second surface B of wheel 20 and which tends to raise the free end 28 of blocking finger 25 to a position such that when no action is exerted on safety spur 24, spur 24 will be held by spring 27 at the top end of slot 23' and boss 26 will be in the path of swinging movement of free end 28.
- the first surface A of the wheel 20 comprises also a shaft 29 located on the periphery of wheel 20 and situated at the apex of a triangle passing through the abutment lugs 22 and 23.
- a swinging lever 30 is freely mounted about this shaft 29 in pendulum fashion.
- the free end 31 of this swinging lever 30 has for example a rounded shape.
- the second lug 23 as well as the safety spur 24 of the wheel 20 are disposed in the interior of the catch 6 of the hook 4.
- the wheel 20 having on its first surface A the shaft 29 on which is movably mounted the swinging lever 30, said swinging lever 30 moves from the position shown in FIG. 1 to the position shown in FIG. 2.
- the shaft 29, on which is mounted in pendulum fashion the swinging lever 30, effects a movement of rotation limited by a shoulder 32 of the hook 4 (shown in broken lines).
- the shoulder 32 is adapted to come into abutment against the forward surface 2 of the oven when the movable door 3 completely closes the chamber, a distance d between said shoulder 32 and the inside surface of the catch 6 adjacent the nose 5 being thus defined with precision by the manufacturer to effect complete closure of the door 3 without any play.
- This pivoting movement of swinging lever 30 is effected, for example, by a vane 34 movably mounted for rotation about a pivot axis 35. The rotation of this vane, in the direction of arrow F4, is brought about, for example, by operating button 36 which is the actuating button of the microwave oven situated on the control panel and partially illustrated.
- the nose 5 of hook 4 upon closure of the movable door 3 on which is fixed the hook 4, the nose 5 of hook 4 effects a movement of rotation about the swinging axis of the door in the direction of arrow F1.
- Nose 5 engages in opening 9 in the forward surface 2 of the microwave oven and strikes the first lug 22 of the wheel 20.
- the blocking finger 25, shown detached from wheel 20 for better understanding is located adjacent boss 26 to come into contact with this latter if no force is exerted on safety spur 24.
- the closing of the door having taken place, as shown in FIG. 3a, the force F1 exerted on the first lug 22 drives the wheel 20 in rotation.
- the nose 5 of the hook exerts by its lower portion, on the safety spur 24, an action in the direction of arrow F2.
- the blocking finger 25 is movably mounted on an axle 37 on the second surface B of the wheel 20, under the action of spring 27 comprising two ends 38 and 39, one 38 being connected to the blocking finger 25, the other 39 being connected to the wheel 20, this connection being schematically shown in the exploded views 3a, 3b, 3c.
- the swinging of the safety spur 24 and the rotation of the wheel 20 permit the blocking finger 25 to pivot and retract, thereby avoiding the boss 26 which would limit the angular displacement of the wheel 20 when no force is exerted on safety spur 24.
- FIG. 2 The final position of the wheel 20 after complete closure of the movable door 3 of the microwave oven is shown in FIG. 2.
- the finger 25 has a hole 40, parallel to the safety spur 24 and which permits reception of the shaft 37 on the second surface B of the wheel 20.
- the wheel 20 has its mounting shaft 21 mounted rotatably in a hole 42 provided in plate 14.
- a lock washer (not shown) secured on the end of shaft 21 after its engagement in hole 22 on the other surface (not shown) of the plate 14 permits the axial positioning of the wheel 20 on the plate 14 while leaving the wheel 20 free to rotate about the shaft 21.
- Wheel 20 is limited in its angular displacement by the hook 4 of the movable door 3 of the microwave oven. Moreover, to draw the hook 4 toward the interior of the oven, and thus to apply the door against the forward surface, the wheel 20 and thus the first lug 22 are subjected to a rotative drive device comprising a tenon 43 mounted on the second surface B of the wheel 20 and disposed in alignment with the shaft 29 on the first surface A of the wheel 20, said tenon 43 passing along a slideway 44 provided in plate 14.
- the outwardly extending end 45 of the tenon 43 is secured to a first end 46 of an over-center toggle 47 under the influence of a spring 48 and shown in broken lines because it is disposed on the other side of plate 14, while a second end 49 passes through a support 50 fixed to and integral with the plate 14 and serves as abutment for the spring 48 as well as a sliding bearing for the toggle 47.
- the tenon 43 of the wheel 20 passes from a first position shown at 51 showing the axis of tenon 43 when no force is exerted on the lugs 22 and 23 or on safety spur 24, to a second position shown at 52 showing the axis of tenon 43 after the exertion of force on the recited elements.
- An arrow 53 shown in slideway 44 describes the movement of rotation undergone by the tenon 43 of the wheel 20 when the blocking finger 25 of the wheel 20 is retracted, thereby avoiding abutment with the boss 26 and permitting the continued rotational movement of wheel 20.
- buttons can actuate the rotation of the swinging lever 30 to operate the starting switch 15 of said oven, for example, the button of a preprogrammed timer of a microwave oven of the type described, for example, in French patent application No. 2 630 613 or an electronic button of a microwave oven, but in these latter cases, it is necessary to adapt the position of the appropriate mechanisms, not illustrated, to permit operation of the device.
- the device according to the invention is applicable to microwave ovens but could equally be applicable to other apparatus requiring very reliable safety.
